A common English plant: it flowers in the midst of summer. It grows to a foot or more in height; the leaves are winged, and the flowers are yellow. The root is perennial; the leaves are hairy, of a pale green, and notched at the edges; the stalk is single, firm, and round; the flowers stand in a long spike; they are small and numerous, and the seed-vessels which succeed them are rough like burs. The plant is common about hedges.
The leaves are used fresh or dried; they have been recommended in the jaundice; but they are found by experience to be good in the diabetes and incontinence of urine. The plant is also one of the famous vulnerary herbs, and an ingredient in the right arquebusade water.
The Family Herbal, 1812, was written by John Hill.
